Ninty!

3DS Revealed. Finally. Iwata has finally unveiled the 3DS... and whilst the details don't really come as much of a surprise, it's shaping up to be a very sexy piece of kit. The device conforms exactly to the recent leaked specifications- and in fact, Kotaku's photoshop mockup was right on on the money. However, it will be able to take 3D pictures and display downloadable 3D movies (with a WB and Disney partnership in the pipeline). Backwards compatibility and a seriously impressive third party commitment will ensure that the 3DS will make us very happy indeed... and will make Nintendo a lot of money. Launch titles will include a new 3D Kid Icarus.

Kojima announces MGS Snake Eater 3DS Remake. Yeah, that's right. Apparently a fully-featured remake of MGS Snake Eater is headed to the 3DS. This is something we want. Right now.

Zelda: Skyward Sword Revealed and demoed. Thelatest iteration of the Zelda franchise, titled Skyward Sword, features 1:1 sword and shield combat facilitated by the Wii MotionPlus. However, Tech issues (or a buggy alpha build, go figure) caused Shigsy to cancel a couple of the demonstrations- but you'll get the gist of it. The Wiimote controls the sword, allowing the player to swipe, lunge, parry and hold the sword aloft to charge up a powerful attack (hence the title). Let's face it: poor demo aside, it's going to be good. It's a Zelda game after all.

Kirby Epic Yarn Unveiled. Kirby's back... and this time, the gimmick is string.This is actually shaping up very nicely, with a distinctive visual style and some epic boss battles.

Wii Donkey Kong Revealed for holiday release. That's right: the big guy's back for another 2.5D outing. No real surprises, but another quality platformer is always worth getting excited about.

Goldeneye 007 Dated for November.Activision's (fairly ugly) revival of Rare's classic shooter has been officially dated for November. Personally I'm not sure that anything good can come of this... but I'd love to be proven wrong.

Epic Mickey Shown off by Spector. A violent fan backlash forced Warren to go back to his drawing board after the woeful Wii screenshots were released last year... and it shows.

Golden Sun: Dark Dawn Announced for DS. The original Golden Sun is still revered by handheld gamers as a pinnacle of portable storytelling, and the new sequel will deliver isometric 3D graphics and some shiny effects. One to watch.

Sony!

Playstation+hitting PSNsoon. Whilst this didn't surprise us in the least, Sony's premium subscription PSN service will be hitting very soon. Standard PSN services (such as messaging and online play) will continue to be free for regular PS3 owners... but the subscription offers a slew of perks including free PSN downloads, early demo access and Qore membership. At around £35 per year, this is quite an attractive little package.

Portal 2 and Steamworks Heading to PS3. You know the "big surprise" that Valve have been teasing us with these last few days? Portal 2 is headed to the PS3. The addition of Steamworks to the PS3's repertoire will apparently ensure that the PS3 version is "the best version of the game." Gabe Newell's words, not mine. Expect a 2011 launch.

Playstation Move works, Dated and Demoed. Unlike Microsoft's fairly insubstantial Kinect demo and Nintendo's impotent Wiimote issues, Playstation Move actually worked convincingly. It's set to launch September 15th with a $49.99 price tag and over 40 developers lined up to support the peripheral. Sorcery, a newly-announced title, uses the Move controller to control a selection of powerful spells with full 1:1 wand control. I'm personally still not fussed by the move (no pun intended) towards motion control, but at least Sony's offering seems to handle fairly well.

Sample Move Games Selection Revealed. There's no quick and easy way to do this... so here we go! Time Crisis, Singstar Dance, Echochrome 2, Eyepet, Bruswick Bowling, Fight Night, Sports Champions, Move party, Heroes on the Move, Socom 4, The Shoot, Tron and Sorcery are headed to the PS3 in the near future.

GT5 Dated for November. Yamauchi's nearly ready to release his latest magnum opus. It's looking very shiny- but we hope that it won't trade fun for realism.

Heroes on the Move Revealed. Ratchet, Clank, Sly Cooper, Daxter and Jak will be united in the platformer that literally nobody wanted. I just hope we get the chance to properly throw down on some of the most annoying and grating characters in videogame history. Move support confirmed.

PSP will "Up its Game." The PSP has been slowly dying for several years now thanks to inconsistent software support- but Sony has vowed to reinvigorate its flagging handheld. They've promised to deliver 70 new PSP titles before Christmas as well as some killer apps including MGS Peace Walker and God of War: Ghosts of Sparta. It's about time they showed the PSP some serious love.

Twisted Metal is happening.David Jaffe has been staunchly denying that a new Twisted Metal's been in the works- but it turns out that his pants have been on fire this whole time. Multiplayer is looking exceptionally well-featured.

And that's a wrap. Frankly, my fingers are cramping up and my mind has been truly blown by today's proceedings- so I'd like to open the floor to all of you. What did you make of the Nintendo and Sony pressers? What're you most excited about? Who, in your opinion, is winning E3 so far? Drop us a line in the comments!
